Data collection
Enrollment in DD2 is based on a questionnaire (including a part with a few questions for the patient and a part to be filled out by the enroller) and the collection of a urine sample and a blood sample. All individuals older than 18 years of age diagnosed with diabetes within the last 2 years are eligible for inclusion in DD2 (previously, a longer diabetes duration was allowed).
The individual can either sign up online (and then be contacted) or be approached by the practice personnel (e.g., during a regular diabetes check-up). The individual will receive an e-mail with a link to WebPatient, where a few questions should be filled out before the questionnaire will be sent to the practice. Hereafter, a DD2 examination will take place, where additional questions will be answered (e.g., a clinically assessed diabetes debut date) along with a physical examination (e.g., weight, hip and waist circumference, resting heart rate). The examination also involves a urine sample (morning urine) and a blood sample (fasting).
Enrollment can either take place in the practice/GP or in the outpatient clinic. Registration is also possible for individuals without internet access. For further information about the enrollment, please see the DD2 website (Danish): Patient information and Instructions and questionnaires.
